STEEL conNnerING-non.

Specification of Letters Iatent.

Patented Oct. 24, 1911.

Application filed February 23, 1910. Serial No. 545,539.

Indiana, have invented a certain new and useful Steel Connecting-Rod; and I do clear, and exact description thereof, refer- J ence being had to the accompanying drawmgs.

Theobject of this invention is to improve the construction of connecting rods and bearings therefor to'be used on gasolene enhalves similarly formed and centrally bent gines and the like.

The chief feature of this invention consists in aconnecting rod formed essentially of a single piece of metal with the two ends or to bring the two halves thereof together and electrically weldingthe same, the central portion, where the bend occurs, forming an eye, and the other end adapted separately or with another piece to form another eye for fitting on bearings, shafts or the like. This makes an-extremely strong and convenient connecting rod; In addition to the foregoin is the means for tightening the bent end 0 the connecting rod so as to bring it in smooth engagement with the shaft or boxing on which it may be mountwill be taken up ed. The large end is preferably formed by adding a semi-circular part, the parts being .united together by clamping bolts through flanges, and one of said parts having a punched out opening adapted to register with an opening in the bushing, whereby .oil during the revolution of the crank shaft on which said part may be mounted in an engine. Along with the foregoing is a'peculiar arrangement of bushing for completing the connecting rod,

The nature of-the invention Wlll be understood from the accompanying drawings and the following description and claim.

- rod in completed form, the remainder being broken away; Fig. 6 is a central vertical section through Fig. 5. Fig. 7 s a plan;

view of Fig. 5.

The major portion 10 of said connecting rod is formed of a singlepiece of metal,-with the central portion 11 thereof flattened and their length, as shown in Fig, 1. When said 7 bar is bent, these two halves are electrically welded so as tomake a practically solid rod between the ends. The central portion 11 of the bar, when thus bent, forms an eye adapted to be mounted on a shaft or pin in the piston, and the portion. of the rod adjacent said eye 11 is centrally and longitudinally out out to form the slot 12, and through said portion of the rod a tightenin bolt 13 extends whereby said eye 11 may e tightened down to make a .properand satisfactory seat on the pin or shaft, on which it is mounted. The extreme ends '14 of the bar from which the rod is made are similarly bent, curved or formed quadrant-shaped so that when they are brought together, asshown in Fig. 1,. they will be semi-circular and will coiiperatewiththe detached portion 15, for forming an enlarged eye for mounting the rod on the crank shaft 16 or other shaft, as desired. The part 15 is secured to the parts 14 of the. connecting rod by screws 17 as seen in Fig.6.

The enlarged portion of the connectingrod contains a bushing formed of two semi-circular halves 20- and 21, each centrally and 'holes 23 whereby it is secured to the main portion of the connecting rod by rivets 24.

The other half 21 of the bushing is provided with an opening 25 which registers with an opening 26 punched out ofthe detached member 15 of the connecting rod. The

' punched out tongue 27-projects tangentially so that as the crank shaft 16 revolves, the tongue 27' will catch oil ,in the crank casing and cause the oil "to be thrown through the openings 26 and 25, and thus the hearing between the bushing 21 and the'crank shaft, will be kept lubricated.

What I claim'as my invention and desire to secure by Letters Patent. is:

A pressed-steel. connecting rod for engines consisting of 'a central body portion formed of two longitudinal parts welded together,

ing the material constituting said connect ing rod and the other end of each Welded half of said connecting rod spread in the are of a circle, a semi-circular member, said semi; circular member having a tongue punched out of the same centrally, means for secui ing said member to the bifurcated end of the connecting rod, and a split bushing with one hzzif riveted to the spread end of the concnecting rod and the other half provided with a hole that registers with the punched out opening through said semi-circular member.

In Witness whereof I have hereunto af- 15 fixed" my signature in the presence of the Witnesses herein named.
